亚超声遥控电路的制作与故障分析

Analysis on the production of ultrasonic remote control circuits and problems

亚超声遥控电路作为电子测量、电子制作课程的实训项目,其电路不仅实用性强,而且综合了电容降压、整流滤波、选频放大、双稳态翻转等.亚超声控制电路适用于实训教学,但是亚超声电路如果制作或使用不当,会产生一些故障,如何分析判断解决这些电路故障,保证电路的安全持续使用,是相关人员所必须解决的问题.

As training programs in electronic measurement and electronic production class, ultrasonic remote control circuits is not only practical, but also a combination of capacitor step-down, rectifier, filter, frequency selective amplifier and bistable flip; Ultrasonic control cir- cuit is suitable for the practical teaching. However, some problems will arise due to improper operation, how to solve these problems and ensure safety of the circuit are issues we must deal with.
